Java Programming With Lambda Expressions

Introduction Java Programming With Lambda Expressions

Java Lambda expressions are a new and important feature included in Java SE 8. A lambda expression provides a way to represent one method interface using an expression. A lambda expression is like a method, it provides a list of formal parameters and a body (which can be an expression or a block of code) expressed in terms of those parameters. Lambda expressions also improve the Collection libraries.

Java Programming With Lambda Expressions Job Support

Java SE 8 added two packages related to bulk data operations for Collections, the java.util. function package, and the java.util.stream. A stream is like an iterator, but with a lot of extra functionality. Taken together, lambda expressions and streams are the biggest change to Java programming since the generics and annotations were added to the language.

In this article, we will explore the power of lambda expressions and streams, from simple to complex examples.A very brand new and exciting feature, java 8 ship with it, is Lambda expressions. They are not unknown to many of us who have worked on advanced languages like scala.

In fact, if you look at history and try to find out any language improvement in java in last 2 decades, you will not be able to recall many exciting things. Only few concurrent classes, generics and if you agree then annotations as well, are remarkable additions in java in last decade. Lambda expressions break this drought and feels like a pleasant gift.
